"So just so you know, when we first started filming the show — I came in at Season 3 — we didn't have hair and makeup. We didn't have, like, a glam team to get us together," Tamra said (clip above). "So I put that yellow shirt on and those earrings and that scarf, and I thought, 'This is the sh**.'"

But just because Tamra has a rationale for why that outfit happened doesn't mean she regrets wearing it any less. "Oh my gosh. Now I look back, and I'm like, 'What was I thinking?'" she admitted, adding that the look was "horrible."

That's not the only fashion miss Tamra has had on RHOC over the years. "I have had a lot of moments like that. I think I had one with big purple sleeves. We wore the sky tops a lot back then. I don't even know if they're still in business. But yeah, lots of fashion no-nos," she said of the cast's fashion staple in the early days of RHOC. "The sky tops were cute for their time, but we overdid it. It's, like, too much of a good thing. It was time to move on."

But Tamra is definitely looking smoking hot these days. Check out her unbelievable body transformation, below.
